Abstract
A backplane printed circuit board (1) is metal-ized on its outer side with a shielding layer (2) on which a metal body (16) is applied over a large area, said metal body having an aperture for the plug connec-tion. A shielding sleeve (17), which covers over the plug parts of the plug connection in the manner of a cap, is screwed into the aperture of the metal body (16). The module frame is hence shielded against the penetration of interfering radiation.

T~(T TRANS~AJION
Plug conn~ction for a light guide which can be connected to a module frame The invention relates to a plug connection for a light guide which is connected to a plug having a center-ing pin which is plugged into a centering bu~h of aholding body which is secured to a back~l~n~ printed circuit board of an electrical module frame, the back-plane printed circuit board being provided with free holes for the plug connection.
A plug connection of this type has been dis-closed, for example, in DE 9010 866 Ul. According to the latter, the plug has a union nut which can be screwed together with a threaded piece ro~nected to the centering bush. The union nut extends from a central ~ection of the plug to beyond the centering pin. It is throughout knurled for the purpose of manual actuation.
- In modern bro~h~nA switching technology, it is normal to provide the backplane printed circuit boards with shielding layers over a large area for the purpose of shielding. Since the plug connection of the light guide must remain largely free from external forces, the plug connector parts are inten~e~ not to touch the backplane printed circuit board. Between the shielding layer and the plug connector parts there therefore exists a gap which reduces the ~uality of the shielding, especially since the plug ~onnector parts are not connected to ground.
The invention is based on the object of increas-ing the shielding rel; ~h; 1; ty.
This object is achieved by means of the invention according to claim 1. A large-area and intensive contact can be produced between the stable metal body and the external shielding layer, ~ 2~0~2 ~, as a result of which the backplane printed circuit board is completely sealed along the shielding layer. The shielding sleeve can be connected to the metal body in a radio-frequency-tight manner, for example by means of screwing into the latter. It can be connected to the plug, for example by its other end, 80 as to give a contact, so that the gap between the plug and the shield-ing sleeve is sealed.
However, there is also the possibility of extend-ing the shielding sleeve b~yO~d the plug, as a result ofwhich the gap between the shielding sleeve and the plug becomes 80 long that extensive ~hielding is achieved. The shielding sleeve, in this arrangement, can be designed such that it closely surrounds the plug and/or the incoming light guide, as a re3ult of which forces acting laterally on the plug are intercepted and cannot influence the sensitive plug connection.
- Advantageous developments of the invention are characterized in claims 2 to 11.
- 20 As a result of the development according to claim 2, virtually complete sealing is achieved between the plug parts and the shielding sleeve. In this arrange-ment, the internal diameter of the shielding ~leeve can be 80 large that the plug parts are not contacted, 80 that the plug connection remains uninflllenc~ by corre-spo~; ng lateral forces.
As a result of the development according to claim 3, it is possible to mount the shielding sleeve on the backplane printed circuit board before the insertion of the plug, in a suitable assembly stage, and subse-quently to lead the plug for the light guide through the shielding sleeve, in order to insert the centering pin into the centering bush. The correspo~; ng gap i8 then effectively sealed by means of the contacting spring tongues.

A large-area and intensive contact can be produced between the stable metal body and the external shielding layer, ~ 2~0~2 ~, as a result of which the backplane printed circuit board is completely sealed along the shielding layer. The shielding sleeve can be connected to the metal body in a radio-frequency-tight manner, for example by means of screwing into the latter. It can be connected to the plug, for example by its other end, 80 as to give a contact, so that the gap between the plug and the shield-ing sleeve is sealed.
However, there is also the possibility of extend-ing the shielding sleeve b~yO~d the plug, as a result ofwhich the gap between the shielding sleeve and the plug becomes 80 long that extensive ~hielding is achieved. The shielding sleeve, in this arrangement, can be designed such that it closely surrounds the plug and/or the incoming light guide, as a re3ult of which forces acting laterally on the plug are intercepted and cannot influence the sensitive plug connection.
- Advantageous developments of the invention are characterized in claims 2 to 11.
- 20 As a result of the development according to claim 2, virtually complete sealing is achieved between the plug parts and the shielding sleeve. In this arrange-ment, the internal diameter of the shielding ~leeve can be 80 large that the plug parts are not contacted, 80 that the plug connection remains uninflllenc~ by corre-spo~; ng lateral forces.
As a result of the development according to claim 3, it is possible to mount the shielding sleeve on the backplane printed circuit board before the insertion of the plug, in a suitable assembly stage, and subse-quently to lead the plug for the light guide through the shielding sleeve, in order to insert the centering pin into the centering bush. The correspo~; ng gap i8 then effectively sealed by means of the contacting spring tongues.
2~50~2 As a result of the development according to claim 4, contact surfaces are produced on the originally knurled union nut, in order to be able to contact said contact surfaces with the sh;el~;n~ sleeve.
As a result of the development according to claim 5, it i possible to be able to actuate the union nut in an easy to grasp manner, even if other plug connectors are arranged closely adjacent.
As a result of the development according to claim 6, the shielding sleeve is secured in a radio-frequency-tight and stable manner to the metal body.
As a result of the development according to claim 7, the gap between the plug and the metal body and/or the sh;el~;ng sleeve is already reliably sealed in the vicinity of the shiel~;ng layer. As a result of the cylindrical configuration of the contact section, the spring fingers can be displaced with respect to the plug - to such an extent that ~h;ckn~ss differences of the backplane printed circuit board are compensated for.
- 20 As result of the development according to claim 8, it is possible to arrange the plug connections, as required, freely alongside or between other electrical plug connectors. In this arrangement, the free holes and the apertures in the metal body can be designed such that plug connections and/or co~ l plugs can be optionally accommodated.
As a result of the development according to claLm 9, both the holding body and the metal body can be secured to the printed circuit board with the same screws. The projecting clamping pins already fix the holding body to the printed circuit board before screwing on, as a result of which assembly is facilitated.
As a result of the development according to claim 10, the screws can be used without a mating thread.
This is produced in the holding body, which consists of plastic, 2~50252 without a particular expenditure of force, for example by using screws with a self-tapping thread.
The lateral ~heek~ according to claim 11 can be proAnce~ without especial addition~l cost by means of corresponding shApi ng tools during injection molding of the holding body or by the use of extruded profiles in the case of the metal body, which consists, for example, of aluminum. They increase the contact surface with the shiel~; nq layer and reduce the length of the hole~ for the holding screws.
~er~;nhelow, the invention is explained in more detail using an exemplary embodiment shown in the draw-ing, in which:
Figure 1 shows in schematic form a longitll~;n~l section 15through a plug co~nection for a light guide in the region of a backplane printed circuit board, having a tubular open shiel~; ng sleeve, Figure 2 shows the parts according to Figure 1 with a cap-like closed shielding sleeve.
- 20According to Figure 1, a backplane printed circuit board 1 is provided with a large-area met~ll; 5 shielding layer 2 and ha~ a free hole 4 in the region of a plug connection for a light guide 3. Attached to said free hole 4, on the inner side, facing the modules 5, of the backplane printed circuit board 1 is a holding body 6 for a centering bush 7 into which there project3 a centering pin 8 of a plug 9 to which the sheathed light guide 3 is connected. A mating plug unit of the module 5 likewise has a centering pin 8 which, in the center of the centering bush 7 abuts at the end onto the centering pin 8 for the light guide 3 and is thus connected to said light guide 3.
The plug 9 is provided with a union nut 11 which abuts a screwed-on stop ring 12. Said union nut 11 has, at its end facing the module 5, an internal thread , 21~02S2 with which it can be 5~-~ eued onto the external thread formed on the centering bush 7. As a result, the stop ring 12 of the plug 9 is ~; A 11y braced between the centering bush 7 and a stop shoulder 13 of the union nut 11, as a result of which the plug 9 with the center-ing pin 8 is fixed to the centering bush 7.
Adjacent to the region of the stop ring 12, the union nut 11 is widened towards the light guide 3 to form a hollow cylindrical sleeve part whose internal diameter is greater than the greatest external diameter of the plug 9. The union nut 11 projects beyond the plug 9 and carries at its free end a knurled actuating section 14 which can easily be re~ch~A by hand, even in the close vicinity of an electrical cable plug 15 plugged onto the backplane printed circuit board 1.
On that side of the backplane printed circuit board 1 which faces away from the holding body 6, a metal body 16, preferably consisting aluminum, is secured by means of screws 10 and contacted by the shielding layer 2. A shielAing sleeve 17 is pushed over the union nut 11 and screwed into an internal thread of the metal body 16. The free end of the contact part 17 is provided with narrow longitllAin~l slits 18, between which spring tongues 19 remain, which are bent towards the union nut 11 and rest on the latter in a contact section 20 which is of smoothly cylindrical design and is located between the actuating section 14 and the stop ring 12. As a result, a close ground contact, which largely prevents the penetration of interfering radiation through the backplane printed circuit board 1, is produced between the shiel~in~ sleeve 17 and the union nut 11, which consists, for example, of brass or nickel silver.
According to Figure 2, the tllh~ r open shielAing sleeve 17 of Figure 1 is substituted by a cap-like shielding sleeve 17 which is extenAeA beyond the union nut 11 and exposes only a ~ 21~0~2 narrow opening for the penetrating sheathed light guide 3. The gap between the shielding sleeve 17 and the union nut 11 is so narrow and 80 long that effective shi~ ing is already achieved. The shielrl;ng sleeve 17 has, at its free end, a freely accessible knurled grip surface 23 and, in addition, wrench surfaces 24 for the attachment of a corresro~;ng tool.
On the other side of the shielding sleeve 17, between its end and a ~ho~ r of the metal body 16, there is cl ~r~ a circumferential external collar of a contact sleeve 25 which rests with longit~ ;n~lly extend-ing spring fingers 26 on the union nut 11 which, in this contact section 20, is of a smoothly cylindrical design.
As a result addit;orl~l sealing is achieved between the union nut and the sh;~l~;ng sleeve 17. The contact sleeve 25 can be longitll~l;n~lly displaced on the union nut 11, 80 that ~h;ckn~a3 differences of the printed circuit board 1 can be compensated for without changing the contact properties.
- 20 The metal body 16 and the holding body 6 are provided with lateral web-like cheek~ which enlarge the bearing surface with respect to the backplane printed circuit board 1. The thread-tapping screws 10 are arranged in this region and are screwed into holes of the holding body 6, which consists of plastic. Said holding body 6 has projecting clamping pins 27 which are pressed into corresponding clamping holes of the backplane printed circuit board 1 and fix the holding part 6 before screwing firmly to the backplane printed circuit board 1.
As a result of the development according to claim 5, it i possible to be able to actuate the union nut in an easy to grasp manner, even if other plug connectors are arranged closely adjacent.
As a result of the development according to claim 6, the shielding sleeve is secured in a radio-frequency-tight and stable manner to the metal body.
As a result of the development according to claim 7, the gap between the plug and the metal body and/or the sh;el~;ng sleeve is already reliably sealed in the vicinity of the shiel~;ng layer. As a result of the cylindrical configuration of the contact section, the spring fingers can be displaced with respect to the plug - to such an extent that ~h;ckn~ss differences of the backplane printed circuit board are compensated for.
- 20 As result of the development according to claim 8, it is possible to arrange the plug connections, as required, freely alongside or between other electrical plug connectors. In this arrangement, the free holes and the apertures in the metal body can be designed such that plug connections and/or co~ l plugs can be optionally accommodated.
As a result of the development according to claLm 9, both the holding body and the metal body can be secured to the printed circuit board with the same screws. The projecting clamping pins already fix the holding body to the printed circuit board before screwing on, as a result of which assembly is facilitated.
As a result of the development according to claim 10, the screws can be used without a mating thread.
This is produced in the holding body, which consists of plastic, 2~50252 without a particular expenditure of force, for example by using screws with a self-tapping thread.
The lateral ~heek~ according to claim 11 can be proAnce~ without especial addition~l cost by means of corresponding shApi ng tools during injection molding of the holding body or by the use of extruded profiles in the case of the metal body, which consists, for example, of aluminum. They increase the contact surface with the shiel~; nq layer and reduce the length of the hole~ for the holding screws.
~er~;nhelow, the invention is explained in more detail using an exemplary embodiment shown in the draw-ing, in which:
Figure 1 shows in schematic form a longitll~;n~l section 15through a plug co~nection for a light guide in the region of a backplane printed circuit board, having a tubular open shiel~; ng sleeve, Figure 2 shows the parts according to Figure 1 with a cap-like closed shielding sleeve.
- 20According to Figure 1, a backplane printed circuit board 1 is provided with a large-area met~ll; 5 shielding layer 2 and ha~ a free hole 4 in the region of a plug connection for a light guide 3. Attached to said free hole 4, on the inner side, facing the modules 5, of the backplane printed circuit board 1 is a holding body 6 for a centering bush 7 into which there project3 a centering pin 8 of a plug 9 to which the sheathed light guide 3 is connected. A mating plug unit of the module 5 likewise has a centering pin 8 which, in the center of the centering bush 7 abuts at the end onto the centering pin 8 for the light guide 3 and is thus connected to said light guide 3.
The plug 9 is provided with a union nut 11 which abuts a screwed-on stop ring 12. Said union nut 11 has, at its end facing the module 5, an internal thread , 21~02S2 with which it can be 5~-~ eued onto the external thread formed on the centering bush 7. As a result, the stop ring 12 of the plug 9 is ~; A 11y braced between the centering bush 7 and a stop shoulder 13 of the union nut 11, as a result of which the plug 9 with the center-ing pin 8 is fixed to the centering bush 7.
Adjacent to the region of the stop ring 12, the union nut 11 is widened towards the light guide 3 to form a hollow cylindrical sleeve part whose internal diameter is greater than the greatest external diameter of the plug 9. The union nut 11 projects beyond the plug 9 and carries at its free end a knurled actuating section 14 which can easily be re~ch~A by hand, even in the close vicinity of an electrical cable plug 15 plugged onto the backplane printed circuit board 1.
On that side of the backplane printed circuit board 1 which faces away from the holding body 6, a metal body 16, preferably consisting aluminum, is secured by means of screws 10 and contacted by the shielding layer 2. A shielAing sleeve 17 is pushed over the union nut 11 and screwed into an internal thread of the metal body 16. The free end of the contact part 17 is provided with narrow longitllAin~l slits 18, between which spring tongues 19 remain, which are bent towards the union nut 11 and rest on the latter in a contact section 20 which is of smoothly cylindrical design and is located between the actuating section 14 and the stop ring 12. As a result, a close ground contact, which largely prevents the penetration of interfering radiation through the backplane printed circuit board 1, is produced between the shiel~in~ sleeve 17 and the union nut 11, which consists, for example, of brass or nickel silver.
According to Figure 2, the tllh~ r open shielAing sleeve 17 of Figure 1 is substituted by a cap-like shielding sleeve 17 which is extenAeA beyond the union nut 11 and exposes only a ~ 21~0~2 narrow opening for the penetrating sheathed light guide 3. The gap between the shielding sleeve 17 and the union nut 11 is so narrow and 80 long that effective shi~ ing is already achieved. The shielrl;ng sleeve 17 has, at its free end, a freely accessible knurled grip surface 23 and, in addition, wrench surfaces 24 for the attachment of a corresro~;ng tool.
On the other side of the shielding sleeve 17, between its end and a ~ho~ r of the metal body 16, there is cl ~r~ a circumferential external collar of a contact sleeve 25 which rests with longit~ ;n~lly extend-ing spring fingers 26 on the union nut 11 which, in this contact section 20, is of a smoothly cylindrical design.
As a result addit;orl~l sealing is achieved between the union nut and the sh;~l~;ng sleeve 17. The contact sleeve 25 can be longitll~l;n~lly displaced on the union nut 11, 80 that ~h;ckn~a3 differences of the printed circuit board 1 can be compensated for without changing the contact properties.
- 20 The metal body 16 and the holding body 6 are provided with lateral web-like cheek~ which enlarge the bearing surface with respect to the backplane printed circuit board 1. The thread-tapping screws 10 are arranged in this region and are screwed into holes of the holding body 6, which consists of plastic. Said holding body 6 has projecting clamping pins 27 which are pressed into corresponding clamping holes of the backplane printed circuit board 1 and fix the holding part 6 before screwing firmly to the backplane printed circuit board 1.
